The present invention concerns oxidative degradation of polysaccharides, and provides a composition, kit, and method for increasing the efficiency of recalcitrant cellulose degradation, using an auxiliary activity family 7 (AA7) enzymes and a polysaccharide monooxygenase enzyme (E.C. 1.14.99.-). Said AA7 enzyme comprises dehydrogenase activity (E.C. 1.1.1.-) and gluco-oligosaccharide oxidase activity (E.C. 1.1.3.-) and provides a novel "functionality" within a previously not described clade of AA7 dehydrogenases.
